Differential encoder hard crashes the PC MESA7i77

Here we are! I super appreciate it...so does my wife   Ive been trying to make this work all day

The problem is this:

Region 0: Memory at fce00000 (32-bit, non-prefetchable) [disabled] [size=64K]

Which is likely something the BIOS did so may be fixable if you have access to BIOS PCI settings
I will take a look into what is needed to get mesaflash to re-enable the memory region (lLinuxCNC does this)

I do have access to some BIOS PCI settings, but not sure if I can screenshot them. I am afraid the best I can do is take a picture. 

I did some searching...will this command do anything for me?

the options in my BIOS PCI Subsystem Settings are:
Above 4G Decoding (enable/disable)
SR-10V Support (enable/disable)

and in BIOS Onboard Device Configuration
PCIEX1_1 Mode (auto) <--but i think this only refers to speed. I have this selection/option for all the PCI slots on the board

I tinkered with all of these earlier today to no result. I do have an ASUS A520M motherboard...BIOS options seem pretty generic.

You could try  setpci and verify if the [disabled] goes away from the lspci listing

See if you can disable this in BIOS, it is usually enabled by default

Also, if you are using any kind of PCI-E riser or cable, se the PCI-E speed/mode to GEN1
